"I couldn't ask for a better company or result for my bathroom remodel. It started with my first meeting with Eli, who was very professional, concise and forthright in his presentation to me. It was my third estimate for the project, but.my decision was clear after meeting Eli. I love my new bathroom. The workers were excellent and always left everything neat after each day. The job was completed in 7 days, sooner than projected. Eli helped me with some of the tile choices and was patient when I asked many questions. Thank you so much, Eli"

"We recently had our bathroom remodeled by Be Home Remodeling, and I just wanted to share how happy we are with everything. Pouria, our project manager, was great — super organized, always kept us updated, and really listened to any concerns we had. Any time we needed something or had a question, he handled it right away. The crew (Manuel, Isaí )did an awesome job. They worked cleanly, were respectful of our home, and the quality of the work shows. The bathroom turned out even better than we expected, and we honestly love how everything came out. Overall, it was a really smooth experience, and we’d definitely recommend Be Home Remodeling and Pouria if you’re planning a remodel."

" Zacarias Remodeling Construction did an amazing job on my brand new kitchen! I wanted my kitchen to be done before Christmas and they worked above and beyond to complete it! Oscar (the Owner) would come to see how the project was progressing and inspect the finished work and made sure if we had any concerns or questions. The workers are professional and hard workers!! They also made sure everything was clean before leaving for the day. Suzanne (Estimator/Designer) was there 100% of the time for questions, advice and opinion on the design. Awesome to work with! I am very happy with my kitchen and highly recommend them!"

"We recently had the chance to work with Quartz construction ( owner: Ohad) on our construction project for bathroom remodeling and we couldn’t be more pleased with the results. From start to finish, their team demonstrated professionalism, transparency. They maintained clear communication throughout the project, kept us informed of progress and any potential changes, and delivered everything on time and within budget. The quality of the workmanship is outstanding — every detail was handled with care and precision. What stood out most was their commitment to customer satisfaction. They were responsive to our questions, respectful of our space, and ensured that the final outcome matched our vision perfectly. If you're looking for a reliable, skilled, and trustworthy construction contractor, I wholeheartedly recommend Quartz Construction, Ohad and his team. AJ "

FAQs for addition to existing structure building service projects in Danville, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
